GENERAL DESCRIPTION
The SGM2567A is a small, ultra-low on-resistance load
switch with reverse current protection and controlled
turn-on. The load switch contains an N-MOSFET that
operates over an input voltage range of 2.2V to 5.5V
and can support a maximum continuous current of 4A.
An integrated N-MOSFET offers a low switch R
ON
. The
switch is controlled by ON pin, which is capable of
interfacing directly with low voltage control signals. The
rise time of the device is controlled internally to avoid
inrush current.
The SGM2567A provides reverse current protection by
the ON pin. When the ON pin is pulled to low level, the
device will not allow the current flow through the switch
from the VOUT towards the VIN. This reverse current
protection feature is only active when the device is
disabled by pulling the ON pin to low level.
The SGM2567A is available in a Green WLCSP-
1.45×0.95-6B package.

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure
to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section
is not implied.
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure
to observe proper handling
and installation procedures
can cause damage. ESD damage can range from subtle
performance
degradation to
complete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
